Another object of the invention is to provide a doubling and twistingmachine wherein the cones carrying the spools on which the thread iswound are driven through the use of driving shafts and gearing connectedtherewith.

A further object of the invention is to provide a doubling and twistingmachine wherein the usual belts are eliminated and a particular systemof gearing substituted, the gearing being associated with thread feedingmeans and other parts so that normally all parts will function at thedesired speed, but when any one thread 20 breaks, the mechanismassociated therewith will stop. I

A further object, more specifically, is to provide in a doubling andtwisting machine a set of spreading and feeding rolls arranged tomaintain the threads spread as they leave the feeding spools, and at thesame time feed the threads to the winding spools at a certain rate inproportion to the speed of the winding spools.

Referring to the accompanying drawings by 5 numerals, 1 and 2 indicateend plates forming part of a frame. These plates are connected togetherby suitable bars 3, and also, by suitable top bar 4. These parts allform what may be termed a frame which'carries certain stationary 7 andmoving parts hereinafter fully described. A bracket 5 is connected toplate 1, and on this bracket is mounted a motor 6, which is preferablyan electric motor, connected by suitable coupling 7 to the shaft 8,which shaft carries 15 a sprocket wheel 9 on which a sprocket chain 10operates. This chain 10 also fits on to a sprocket wheel 11 secured toshaft 12, which shaft is connected to suitable gearing hereinafter fullydescribed. Shaft 8 is keyed or otherso wise rigidly secured to a gearwheel 13 (Figure 12) and gear wheel 13 is continually in mesh with thepinions 14 and 15 secured rigidlyrespectively to the shafts 16 and 17..The gear wheels 13 to 15 inclusive are preferably arranged as in a box18, which is preferably supplied with a suitable lubricant. As shown inFigln'e 13, the boxes or compartments 19 and 20 are also supplied with alubricant, which may be atsubstantially any level, but preferably, nothigher than the lower line of the respective gear wheels 21. Arranged atthe end, opposite box 18, is a compartment or box 22, which is suppliedwith oil, and said 011 is usually atapproximately the same level as theoil in the boxes 19 and 20. e5 Shafts 16 and 1'7 carry a number of gearwheels 21, there being one gear wheel for each of the spindles 23(Figure 1). Associated with each .of the gear wheels 21 is a pinion 24,said pinion.

meshing continually with the gear wheels 21'. Preferably, these gearsare of the spiral gear type and are arranged wholly within theirrespective box or compartment 19 or 20. In order to provide a properlubricant to these gears, and also to the gears 13 to 15, supply pipes25 and 106 26 extend longitudinally of the respective boxes 19 and 20and into the box 18 where they discharge on to the respective gears theoil, lubricating these gears, and the excess drips down into the bottomof the box where it is drawn off,

filtered, and again forced through the supply pipes 25 and 26. Inaddition to discharging on to the gears 13 to 15 inclusive, there is adischarge nozzle 27 for each of the gears 21, and a slow discharge iscontinually provided, so that the various gears 21 and 24 are reallyoperating in a bath of oil, though they are not submerged. In this wayample oil is always provided, and yet these gears may be operated athigh speed without heating the oil, which might be the case if they werecompletely submerged. The respective pipes 28 have openings entering therespective boxes 18, 19 and 20, so that the oil may flow, preferably bygravity, into the lower part of the box 22, from which it is pumped bythe rotary pump 29, said pump drawing the oil through the pipe 30 fromnear the bottom of the box 22, and discharging the same through pipe 31.The pipe 31 is connected to a suitable filter 32, which filter may bearranged at any desired point, and the discharge end of this filter isconnected to suitable piping 33 and the pipes 25 and 26. During theoperation of the machine the pump 29 is continually operating as shaft16 carries a pinion 34 continually meshing with the gear wheel 35, whichgear wheel is connected to the operating shaft of the pump. It will beunderstood that this pump may be of any desired kind, but of the rotarytype. In Figures 12 and 13, the various boxes have been shown open, butit is evident that they are to be closed by suitable lids 0r closures,and as illustrated in Figure 3, suitable shoulders or offsets 36 areprovided in each box for the reception of a cover which prevents dirt,dust, and the like from entering.

Referring again to the motor 6 and the way the same drives the sprocketchain 10, it will be seen that the shaft 12 is continually rotatedduring the operation of the motor. This shaft carries a pinion 37 whichmeshes with a suitable train of gears 38, the last of which is a largegear 39, shown particularly in Figures 2 and 5. By reason of thisconstruction and arrangement the gear 39 is continually rotated as longas the motor is in operation. The various gears of the train 38 areproportioned to give a certain speed to the gear 39, and if a differentspeed is desired, one or more of the gears of this train may be changedto secure a different ratio of drive. As shown in Figure 5, the gearwheel 39 is provided with a cone socket 40, and with a hollow stem 41,in'.o which extends the shaft 42. The stem 41 is provided with anannular flange 43 against which the rollers 44 operate. said rollersbeing carried by a fork member 45, said fork member having an internallythreaded stem 46, into which the threaded poriion 47 of shaft 42 isscrewed. A pair of nuts 48 is screwed on to the end of shaft 42, saidnuts being enclosed in a chamber 49 of hand wheel 50. This hand wheel isscrewed on to the stem 46, a suitable set screw 51 acting to lock thehand wheel against rotation independent of the stem 46. The spring 52 isused to normally force the fork member 45 outwardly or away from thegear wheel 39. The cone socket 40 coacts with the cone clutch 53slidably mounted on shaft 42, which is rigidly secured in a suitablefitting 60, said fitting being carried by the end plate 1. The coneclutch 53 carries an eccentric member 54 which is keyed or otherwiserigidly secured thereto. A strap 55 surrounds the eccentric 54 and isprovided with an arm 56, which is connected to the arm 57 (Figure 2) bysuitable pin 58. The arm 57 is rigidly secured to shaft 59, which shaftextends the full length of the machine and coacts with the various stopmotion mechanisms thereof as hereinafter fully described. When the partsare in ihe position shown in Figure 5, the cone clutch 53 is engagingthe cone socket 40, so that the rotation of the gear wheel 39 willrotate the eccentric 54, and, consequently, move the arm 56 upwardly anddownwardly, thus rocking the shaft 59. When it is desired to stop themachine, or for any reason to stop the operation of the shaft 59, thehand wheel 50 is grasped and rotated, whereupon the spring 52 will becompressed and the gear wheel 39 pulled a very short distance away fromthe cone clutch 53, said distance being suificient to produce adisconnection,- whereby there will be no more power transmitted to theeccentric 54. This will not only stop the rocking action of shaft 54 butwill slop the rocking action of the various swinging stops 62 which arerigidly secured thereto. These stops as shown in Figure '7 are providedwith laterally extending arms 63 and 64, and a downwardly extendingabutment 65. When one or more of the threads 66 break, the particularstop mechanism 6'7, carrying said thread, will function to stop therotation of the spindle 23 associated there with, and 5 0p also thefeeding mechanism associated therewith. When the thread has been tiedand the parts readjusted, this part of the machine will start tofunction and con'inue to function until the thread again breaks. Asshown in Figures 6 and '7, two threads 66 are illustrated, but thedevice is made of a size to accommodate one thread, if desired, or morethan two. The detail structure illustrated in Figure 6 could accommodateseven threads, or, if preferred, it could be made larger to accommodateeven more. Where one thread is being used, the same is merely beingtwisted, but if two or more threads are used, they are doubled andtwisted. As illustrated in Figure 6, the two threads are fed through thestop motion mechanism and later doubled and twisted. As illustrated inthis figure and also in Figure '7, these threads pass through suitableeyes 68, each eye being supported by a rod 69 normally resting againstthe bar 70. From these figures, and also from Figure 3, it will be notedthat the threads pass in front of not only bar '70, but also bar '71,and that the guiding eyes 68 are arranged between each bar. Each of therods 69 is rigidly secured to a bell crank lever '72 swingably mountedon the rod '73. The arm '74 of the lever '72 is of suflicient weightthat when a thread breaks it will swing downwardly to the dottedposition shown in Figure '7 and overbalance the eyes 68, so that it willswing to the right, as shown in Figure '7, and add the action of itsweight to the arm '74 to press downwardly the rod '75, which is rigidlysecured to a control-lever '76, which lever is pivo'ly mounted on a rod77 carried by a swinging plate '78. The lever 76 has a weightedextension '79.which is normally positioned to extend beyond theverticalrod 80, said rod being provided with a sleeve 81 rigidly securedto the rod and having an extension 82 provided with a cam surface 83.The plate 78 is pivotly mounted on the rod 84 which is carried by theframe or bracket 85, which frame is bolted or otherwise rigidly securedto the bar 4. Plate '78 is provided with an inclined downwardlyextending cam 86 which normally rests on the top surface 87 of theextension 82. However, when the lever 76 swings downwardly, the weightedend '79 will swing upwardly to the dotted position shown in Figure '7,and, (:Onsequently, the abutment will strike the weighted end 79substantially on the corner 88 and will swing the same to the left asshown in Figure 7, so that the extending cam 86 will be moved oppositethe cam surface 83. This will allow the vertical rod to move upwardlyunder the action of the spring 89 (Figure 1). The swinging stops 62 willcontinue to swing but plate 78 and associated parts will not swing backto their former position because the spring 89 keeps the rod 80 andextension 82 elevated. When it is desired to fix a broken thread, theoperator places his foot on the foot pedal (Figure 1) and in this mannermoves the rod 80 and associated parts downwardly against the action ofthe spring 89. The thread is then repaired and as the extension 86 isresting on the horizontal surface 87, rod 80 cannot move upwardly againuntil the same thread or another thread from the same group breaks,whereupon the same action will take place. This action naturally willtake place when any of the threads 66 in a particular group breaks, and,consequently, the spindles 23 associated therewith will stop, though theremaining spindles and other parts of the machine will continue tofunction. The same action would take place in case the spools 91 shouldbecome empty. It will be noted that the spools 91 are mounted onsuitable spindles carried by frame 92. In the drawings only two spools91 have been shown, but it is evident that one could be used, or as manyas there are guiding eyes 68 in the stop motion mechanism 67.

It will be understood that the mechanism just described is provided oneach side of the machine because there are two rows of spindles 23.However, each of the stop motion mechanisms operates independently butall coact with the rock shaft 59 and one swinging stop 62 acts for twostop mo'ions, namely, one on each side of the machine.

When the vertical rod 80 moves upwardly as above described, thespindle23 associated therewith will stop. In Figure 4 a detail structureof the lower part of the spindle 23 and associated parts is shown. Allthe o'her spindles and associated parts are made identical. Therefore,the description of this one will apply to all. Referring moreparticularly to Figure 4, it will be seen that the rod 80 is pinned orotherwise rigidly secured to the bracket 93, and also pinned orotherwise rigidly secured to a bar 94, which in turn is pinned orotherwise rigidly secured to the rod 95, having one end sliding in anaperture 96, so as to be guided thereby, the opposite end extendingthrough the bottom pla e 97 (Figure 1) The rod 95 carries a stop 98against which spring 89 presses, said spring also pressing against theplate 97 and continually gives the rod 98 a tendency to move upwardly,and, consequently, gives the vertical rod 80 a continuous tendency tomove upwardly, but said upward movement is prevented by the extension 68(Figure 7) resting on the surface 8'7 of extension 82. The spindle 23 isconstructed in the usual manner of a spindle, namely, in a slightlytapering formation so that the respective spools 99 may be droppedthereon, and by a slight pressure held thereon through the action offriction. At the lower end the spool 99 is provided with an annularshoulder 100 which limits the downward movement of the spool in case thespool should go that far down. Two or more pins 101 preferably extendfrom the lower end of the spool into suitable notches or openings 102 inwhat might be termed a guiding block 103. This block has a centralaperture into which the spindle extension or rod 104 extends, said rodbeing rigidly secured by pin 105 or otherwise to block 103 so that therod and block rotate together. The block 103 is provided with a frictionsurface 106 adapted to be 80 engaged by the leaher or other contactsurface 107 carried in the socket 108 of the bracket 93. It will thus beseen that when the rod 80 is moved upwardly'by the spring 89, the arm 93will be moved upwardly and will move the block 103 and the rod 104upwardly. In addition the friction member 107 will act frictionally onthe block 103 and substantially instantly stop the rotation of theblock, the spindle 23, and the spool carried thereby. It will thus beseen that subslantially 90 instantly upon the breaking of a thread thespool receiving the thread will be stopped. Rod 104 extends downwardlyand is journaled in a sleeve 109, said sleeve being secured by frictionor otherwise to a ubular portion 110 of bracket 111, which bracket has atubular portion 112 at the upper end, said upper end being rigidlysecured by friction or otherwise to a plate 113. The plate 113 formspart of the cover of the box 19, there being other plates associa edwith each spindle to complete the cover structure. An oil opening 114 isprovided in the tubular portion 112 and partly in the journaled sleeve115, which is preferably held in the tubular portion 112 by friction,though it might be secured in some other manner.

It will thus be seen that the .rod 104 is journaled near each end andnear where it merges into spindle 23 is rigidly secured to the block103, and at about the center, it rigidly secured to the cone 116 by asuitable pin. Cone 116 coacts with 110 the cone surface 117 on thesleeve 118, which sleeve is rigidly secured to the pinion 24, whichpinion continually meshes with the gear wheel 21. The cone 116 and thecone socket 117 are so formed that only a slight weight is necessary tosecure ample friction or connection to cause the pinion 24 to drive thecone, shaft 104 and spindle 23 with its spool. However, the spring 89has ample power to quickly raise the rod 80 when permitted and to alsoquickly raise the block 103, the shaft or rod 104, and cone 116, thusproducing not only a disconnection of the power but a braking actionthrough the friction surface 107.

As soon as the rod 80 is permitted to drop down,

or is forced down, by the operator, it will move away from the block103, and this block, spindle 23, and rod 104 will drop down, and theweight of these parts is sufficient to cause the cone 116 to secureample frictional engagement to the cone socket 118 to cause an instantdriving action, 1 provided the machine is functioning.

As a single thread, or two or more threads, are placed in operativeposition, they are given several turns around the tension and guidingrollers 119 and 120, as illustrated in Figures 8 to 11 inclusive. Inorder to prevent the threads from becoming tangled, and also to cause aproper feeding action, rollers 119 and 120 are arranged at certainangles in respect to each other. The roller 119 is preferablysubstantially parallel to the rod 121, which is also substantiallyparallel to the boxes 19 and 20 and rod 59. However, the roller 120 isinclined downwardly and also horizontally toward the roller 119, asillustrated particularly in Figures 9 and 11. This arrangement of roller120 permits the threads to stay separated as they pass around the rollerfrom the respective eyes 68 to the traveller 122. The traveller 122, asshown in Figure 1, is the usual traveller and is carried by the transferbar 123, as shown 7 in Figure 3, the bar 123 being accentuated by therod 124, hereinafter fully described, and carrying a traveller on eachside of the machine so as to coact with two spindles 23. The travellermoves upwardly and downwardly at a certain ratio, as hereinafter fullydescribed, to wind the twisted or doubled and twisted thread on thespools 99. The rod 121 is connected rigidly to the gear 125 forming partof the train of gears 38, shown in Figure 2, so that this rod operatesat a speed in proportion to the speed of the other parts of the machine.As shown in Figure 11, the rod 121 carries a gear wheel 126 whichcontinually meshes with the gear wheels 127 and 128. The teeth of thesegear wheels are suificiently large and loose in their meshing action topermit a ready mesh of gear 128 with gear 126, notwithstanding the factthat they are at an angle. A casing 129 is provided, the same having abracket 130, which is rigidly secured to the rod by any suitable means,as, for instance, by a set screw 131. The casing 129 is provided withtubular portions 132 and 133 which carry bearing sleeves 134 and 135.Shafts 136 and 137 are rigidly secured to their respective gears 127 and128, and also, to the rollers 119 and 120, which rollers telescope overthe tubular portions 132 and 133, but preferably do not contacttherewith. It will thus be seen that the rollers 119 and 120 arepositively driven when the machine is operating and when the verticalrod 80 is in its proper operative position. The rollers 119 and 120 feedthe thread at a cer tain rate of speed, and the spindle 23 operates alsoat a certain speed, while the bars 121 operate at a certain speed, thuspermitting a desired doubling and twisting, or merely twisting wherethere is only one thread involved. It will be noted that there are onlya few bars 123 shown, but, if desired, any desired number could be usedand connected by the longitudinal plates 123 and 123". The respectivebars 123 are rigidly secured to the shafts 124, and these shafts rest onthe outer end of the respective levers 136, which levers have pins 137journaled in a suitable bearing 138. Each lever is provided with aweight 139 which normally keeps the end of the lever in contact with thelower ends of the respective rods 124. An arm 140 is rigidly secured toeach lever 136, said arm being pivotally connected with a pull and pushrod 141, which pull and push rod is pivotally connected to one end ofthe bell crank lever 142, which lever has a free end continuallyoperating on the heart-shaped cam 143. This cam is actuated by a wormgear 144 which continually meshes with the worm 145 and this worm isrigidly secured to a shaft carrying a sprocket wheel 146. A chain 147 isfitted on the sprocket wheel 146 and on to a sprocket wheel 148 rigidlysecured to the rod or shaft 121. In this way power is transmitted by theshaft or rod 121 to the driving and tension rollers 119 and 120, andalso to the mechanism for raising and lowering the respective travellers122. These parts are preferably lowered by gravity, though if desired,spring means could be added to give a positive downward movement.

In operation the machine is intended to function a long period of timewithout stopping. However, any particular spindle and associatedmechanism may be individually stopped at any time to replace or repair athread, or for any other reason. When first starting the machine thehand wheel 50 is. actuated to disconnect the gear wheel 39 from the coneclutch 53, so that the'shaft 59 will not function, but will remainstationary, and the swinging abutment 63 will remain stationary, hangingin a vertical position. As the machine begins to move the rollers 119and 120 will pull on the threads and feed the same to the travellers122. As the rollers thus put tension on the threads, the various eyes 68and associated parts will move outwardly to their operative positions asshown in Figure 7, so that the extension 86 of the plate 78 cannot moveoff of the surface 87. After the parts have been thus automaticallybrought into position, the hand wheel 50 is actuated to permit the coneclutch 53 to function, whereupon the shaft 59 will begin to rock so asto actuate the stop motion mechanism 67 in case one or more threadsbreak. The reason that it is necessary to maintain the shaft 59stationary when starting the machine is to prevent breaking of some ofthe threads. After the parts have been started, as just described, thetension and feed rollers 119 and 120 will pull on the threads to feedthe threads to the spools 99 at the proper speed. While this is takingplace the shafts 16 and 17 are rotating, and, consequently, the variousgear wheels 21 are rotating, and are thereby rotating the pinions 24 sothat the various cones 116, as shown in Figure 4, are rotated, thusdriving the spindles 23 at the desired speed. While this is taken place,the rod or shaft 121 is rotating and power is being transmitted to theheart-shaped cam 143, and from thence to the other mechanism for raisingand lowering the travellers 122. Also, simultaneously with theseactions, the pump 29 is functioning to draw oil from the box 22 andforce the same through the various oil feeding pipes to the variousgears. If the machine is functioning one hundred per cent no attentionneed to be paid thereto, as all the parts operate automatically afterthe machine has once been started. However, if for any reason one of thethreads should break, the stop motion mechanism 67 carrying thatparticular thread will function and the spiridle 23 associated therewithwill stop. As the shaft 80 is raised by the spring 89 to disconnect thecone 116 from its socket, the gear wheels 127 and 128 (Figure 11) willbe lifted off of the gear wheel 126 so that the particular feed rolls119 and 120 will stop rotating, though the shaft 121 will continue torotate so as to actuate the other tension and feed rolls. In case theratio of movement of the shaft 121, and the movement of the travellers122 upwardly and downwardly is to be changed, the sprocket wheels 146and 148 are removed and different sized sprocket wheels substituted sothat there will be a different ratio of drive, though the same chain 147may be used. In this way the speed of the feed of the thread may beincreased or decreased in proportion to the upward and downward movementof the respective travellers 122. It will be noted that the spindles aregear driven and that all belts have been eliminated and various directdriving mechanisms used so that all the parts will function in apositive manner.
